Autosave: The goal of 3.6 is that users should never lose posts because of “expired cookies, loss of connection, inadvertent navigation, plugin or core errors on save, browser crashes, OS crashes, cats walking on keyboards, children drooling in keyboards, etc.” This may include autosaving to the browser’s local storage, and log-in expiration warnings. They are also looking at a post locking functionality to prevent people from overwriting each other’s changes.

Editorial Flow: The features to be added to 3.6 are custom post statuses, which is the ability to add custom statuses like pitch, assigned, in-progress, etc., anddraft revisions, which allow edits to already published posts be saved as drafts before taking place of the original post. They are currently seeking use cases for both features to better understand how they will be used.

Revisions: The revisions tool will get a little TLC — bug fixes, better user interface, and adding visual representation of what was added/removed in each revision.

Is it possible to switch off revision at all? (without plugin) i don’t use it because it push my server and took an additional place. Also i dont like it coz it bloat a DB. Auto-save that work in 3.5 more than enough.
